That doesn't follow. There's nothing that prevents the environment task from 
being non-callable while other tasks are callable.

When the environment task returns from calling the main-program subprogram, it 
becomes completed and non-callable.

It then waits until all dependent tasks complete.

Then it does library-level finalization.

Then it terminates.

There can be a period there when the environment task has completed and some 
dependent tasks have not. Indeed, if any library-level tasks never finish, that 
period can be infinite.
